What EV Charger Do You Need for a 2025 Subaru Solterra?
Many buyers make the mistake of purchasing a 48 amp or 80 amp charger, throwing away money on capacity your car cannot accept. Your 2025 Subaru Solterra caps its Level 2 AC charging at 32 amps. You need a 32 amp home charger paired with a 40 amp breaker.
The numbers
| Maximum AC charging rate | 6.6 kW (32 A) |
|---|---|
| Charger size to buy | 32 A |
| Circuit breaker required | 40 A |
| Outlet / connection | NEMA 14-50 outlet on a 40 A breaker, or hardwired |
| Charge port | J1772 |
| Full charge on Level 2 | about 11.0 hours |
| Range added per hour (Level 2) | about 21 miles |
| Full charge on a 120 V outlet | about 50 hours |
| Range added per hour (120 V) | about 4.5 miles |
| EPA rated range | 227 miles |
| Energy for a full charge | about 72.6 kWh at the wall |
Why 32 amps and not more
The onboard charger dictates what power your vehicle draws from the wall. The Solterra handles a maximum of 6.6 kW, meaning any charging hardware larger than 32 amps goes completely unused by the car. Buying a heavier duty unit buys you zero speed. Your battery holds 72.6 kWh, and refilling from empty takes 11.0 hours on a Level 2 setup. You get 21 miles of range for every hour plugged in. Pushing more current down the line changes nothing for the onboard hardware.
What the install involves
Have a licensed electrician inspect your electrical panel to confirm spare capacity for a new load. They must pull a circuit and land it on a 40 amp breaker to match the requirements. You can use a NEMA 14-50 outlet on that 40 amp breaker, or the electrician can hardwire the unit directly to the supply line. Do not skip professional verification of the wiring gauge and breaker size.

Common questions
- What connector does this car use?
- The vehicle uses a J1772 connector. This model year falls in the industry transition to NACS, meaning many vehicles ship with a NACS port and include a J1772 adapter so standard home chargers still work.
- Can I plug into a normal wall outlet?
- Yes, standard Level 1 charging works on a regular household outlet, but it is painfully slow. Level 1 yields 4.5 miles of range per hour and requires 50 hours to refill the battery from empty.
- Do I need a hardwired unit or a plug-in outlet?
- Both options work fine as long as the circuit matches. You can install a NEMA 14-50 outlet on a 40 amp breaker or hardwire the charger directly.
- What happens if I buy a 40 amp charger like the Grizzl-E Classic?
- It will work without issue. Your car draws its maximum of 32 amps from the unit, ignoring the extra headroom.
